+
+** Bug fixes
+
+*** C++: Fix support of 'syntax_error'
+
+  One incorrect 'inline' resulted in linking errors about the constructor of
+  the syntax_error exception.
+
+*** C++: Fix warnings
+
+  GCC 7.3 (with -O1 or -O2 but not -O0 or -O3) issued null-dereference
+  warnings about yyformat being possibly null.  It also warned about the
+  deprecated implicit definition of copy constructors when there's a
+  user-defined (copy) assignment operator.
+
+*** Location of errors
+
+  In C++ parsers, out-of-bounds errors can happen when a rule with an empty
+  ride-hand side raises a syntax error.  The behavior of the default parser
+  (yacc.c) in such a condition was undefined.
+
+  Now all the parsers match the behavior of glr.c: @$ is used as the
+  location of the error.  This handles gracefully rules with and without
+  rhs.
+
+*** Portability fixes in the test suite
+
+  On some platforms, some Java and/or C++ tests were failing.
